My new best imaginary friend, Kenji Lopez-Alt, has completed a four-week experiment to determine what truth the “McDonald’s Burgers Don’t Rot” meme has behind it. Most serious speculators assumed that the burgers and buns dried out in the air-conditioned interior of an average home. Surprise, surprise – that’s exactly what Kenji discovered. There’s nothing magical about it, just small burgers in a dry environment. Science!
